1. An information transmission method, comprising:
receiving Downlink Control Information (DCI) corresponding to a Physical Downlink Shared Channel (PDSCH), wherein the DCI carries a first parameter, k1 and Physical Resource Indicator (PRI); and
transmitting, according to an indication of the first parameter, a Hybrid Automatic Repeat Request Acknowledgment (HARQ-ACK) corresponding to the PDSCH;
wherein transmitting, according to the indication of the first parameter, the HARQ-ACK corresponding to the PDSCH comprises:
receiving DCIs scheduling one or more PDSCHs, acquiring one uplink unit for transmitting the HARQ-ACK corresponding to the one or more PDSCHs according to the k1 carried in the DCIs, and determining which of the HARQ-ACKs of the one or more PDSCHs belong to one HARQ-ACK codebook according to the indication of the first parameter carried in the DCIs and determining a PUCCH resource corresponding to the HARQ-ACK codebook according to the PRI carried in the DCIs;
wherein the first parameter is used for indicating a HARQ-ACK codebook to which a HARQ-ACK corresponding to a PDSCH belongs;
wherein the k1 is used for indicating a uplink unit for transmitting a HARQ-ACK corresponding to a PDSCH, comprising: in a case where the PDSCH is received in a unit n, the HARQ-ACK corresponding to the PDSCH is transmitted in a unit n+k1;
wherein the PRI is used for indicating a PUCCH resource corresponding to a HARQ-ACK corresponding to a PDSCH;
wherein a PUCCH resource corresponding to a HARQ-ACK codebook is determined according to the indication of the PRI in the last DCI corresponding to the HARQ-ACK codebook.
